EARTH-SC RA PE R.

SPECIFICATION forming part of Letters Patent No. 230,797, dated August3, 1880.

Application filed June 23, 1880.

[0 all whom it may concern:

Be it known that I, \VILLIAM T. MGLEAN, of Sidney, in the county ofShelby and State of Ohio, .have invented a new and useful Improvement inEarth-Scrapers; and I do hereby declare that the following is a full,clear, and exact description of the same.

My invention is an improvement in the class of earth scrapers or scoopshaving a thin metal body, formed preferably of rolled sheet-steel, and awooden back, which is secured to the body by means of clamps, &c.

The improvement consists in the construction and arrangement of thedevices for securing the wooden back to the steel body of the scraper,and in providing the latter with a single longitudinal steelwearing-piece or shoe, which is arranged centrally, and beveled on thesides and front end, as and for the purpose hereinafter specified.

In accompanying drawings, forming part of this specification, Figure 1is a rear view of the scraper, and Fig. 2 a longitudinal section.

The wooden back A is secured to the steel body B of the scraper by meansof the double horizontal brace and tie rod 0 and the vertical braces D.The brace and tie rod 0 consists of two straight parallel parts, a a,which are formed in one piece, which is bent orlooped at the middle. Therod is arranged so that one part, a, extends along theupper edge of thewooden back A, and the part a a short distance below such edge, wherebyit affords both protection and support to the back, as will be readilyunderstood.

Nuts 1) b are screwed on the threaded ends of the rod 0, and serve toclamp the back A firmly between the sides of the body B of the scraper,and also to secure the handles E, one of which is held in the loop ofthe rod O and the other by a yoke or cross-bar, c, that connects theends of the rod.

The vertical braces D are metal bars, which are riveted to the woodenbackA, and provided with loops (1, to receive the lower part, a, of

the double tie-rod O, while their lower ends are reduced in size andpass through and are upset or riveted on the steel body B. Thus the barsD brace and strengthen the back A (No model.)

transversely, and also serve to hold the bottom of the body B snuglyagainst the lower edge of the back A. v

Taken together, the double rod O and bars D constitute a light butstrong compound brace and tie for the back of the scraper.

The shoe or rib F is constructed of steel, and is arranged lengthwise ofthe body B of the scraper and in the center of same. It is also taperedor thinned toward the forward end or point and beveled on the sides, sothat it will have as little friction as possible with the earth. Itreceives a large share of the wear incident to use, and proportionallyrclieves the adjacent portions of the bottom of the scraper, while itadequately strengthens the latter at the point where most required. Itscentral position or location and the absence of side ribs or shoesenable the operator to easily rock the scraper laterally or to hold ittilted laterally while scooping the earth. Moist or other adhesive soilwill not adhere to it or to the contiguous parts of the scraper.

I am aware a single tie-rod and more than one shoe or bottom rib havebeen employed.

What I claim is- 1. In an earth-scraper, the combination, with thewooden back and flexible metal body, of the double tie and brace rod,which is arranged horizontally with one part, a, in rear of said back,and the screw-nuts applied to its ends, as shown and described, for thepurpose specified.

2. The body of the scraper provided with a single wearing piece or shoe,which is attached centrally and longitudinally to its bottom, andbeveled at the front end and on its sides, as shown and described, forthe purpose specified.

3. In an earth-scraper, the combination of the double tie-rod O and nutsI) and the ver tical brace-rods D, having loops, as specified. with thewooden back A, the flexible metal body B, and handles E of the scraper,all arranged substantially as shown and described.
